Many students share the common belief
that the limiting reactant
in a chemical reaction is the reactant in the smallest quantity of
material. To help students overcome this difficulty a hands-on activity
for the limiting reactant concept was developed. The activity incorporates
the three levels of representation (macroscopic, submicroscopic, and
symbolic) and allows students to make connections among them by directly
working at three stations. Each station incorporates one level of
representation allowing students to explore one level of representation
at a time. The focus of the activity is to help students understand
thoroughly the topic of limiting reactant, including concepts related
to it, such as reaction stoichiometry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
